وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ قَالَ مَا صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم الظُّهْرَ وَالْعَصْرَ يَوْمَ الْخَنْدَقِ حَتَّى غَابَتِ الشَّمْسُ ‏.‏ قَالَ مَالِكٌ وَحَدِيثُ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ صَالِحِ بْنِ خَوَّاتٍ أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي صَلاَةِ الْخَوْفِ ‏.‏

Yahya related to me from Malik from Yahya ibn Said that Said ibnal-Musayyab said, "The Messenger of Allah, may Allah bless him andgrant him peace, did not pray dhuhr and asr on the day of the Trenchuntil after the sun had set." Malik said, "The hadith of al-Qasim ibn Muhammad from Salih ibn Khawwat is the one I like most outof what I have heard about the fear prayer." Translation Not Available
